Splitting String (Square Brackets) (C#)

Hello,

I have string which clook like this:
a [213515]

I need a method to split this string and remove the square bracket. With the above example this would produce two strings
a
213515

The approach would have to be able to handle different lengths
I’ve tried using a regex  snippet:

string pattern = @"(?<=\[)(.*?)(?=\])";
Match output = Regex.Match("str_value", pattern, RegexOptions.Singleline | RegexOptions.IgnoreCase);

Open in new window


But this just extracts the contents of the square brackets?
Any suggestions appreciated,

string s = "a [213515]";
            string[] results = s.Split('[');
            results[1] = results[1].TrimEnd(']');

results[0] is "a" and results[1] is "213515"

Your description leads me to this solution:

public static void Main()
{
    string input = "a [213515]";
    string[] result = input.Split(' ');
    foreach (string element in result)
    {                
        Console.WriteLine(element.Replace("[", "").Replace("]", ""));
    }

    Console.ReadLine();
}

I'd use the following regex:
(.*?) *\[(.*)\]

the Split functions accepts all separators as a char array:

string str = "a [123456]";
string [] tokens = str.Split(new Char [] {' ', '[', ']'} );
